Since the existence of Nilgiri hills, bryophyte- the miniatures of plant kingdom play an important and crucial role in the stabilization of Blue Mountains ecology. Unlike Himalayas, the landslides were rare in the area, but with the time and changing global environment it had become a common sight. Significantly ever increasing population and vehicular traffic is the prime reason for them, to cater the need, roads are periodically broadened by cutting road sides destroying the habitat as also the inhabiting species. Bryophytes, are efficient soil binders that regulate the soil moisture and provide substrate for future plant succession. The habitat loss and nudeness of substratum gives impetus to rapid soil erosion that further enhances the problem of their very survival. The present communication provides significance of these avascular cryptogams in environmental assessment, ecological balance and their role in decreasing the pore pressure to check land slides.
Similipal Biosphere Reserve is a part of biotic province of Chhotanagpur Plateau. It has a representative ecosystem under Mahanadian biogeographic region. Its biodiversity is an assemblage representation of Western Ghats and North-East India. Regarding bryophytes this area was rather unexplored and the current investigation shows the occurrence of 33 taxa of bryophytes in this biosphere reserve and its neighboring areas. Each species has been enumerated with its ecological and distributional details.
